I have sex with my stepsister in her nightclothes as she denies me computer access while our parents are in the kitchen; I seize the opportunity to climax briefly before we are discovered

I was denied access to the computer by my stepsister, who was lounging around in her nightclothes. This sparked a desire within me to assert my dominance. As my parents were occupied in the kitchen, I saw this as the perfect opportunity to assert my dominance. I approached her, my arousal palpable, and began to undress her, revealing her luscious pussy. Despite her initial protests, I persisted, taking her from behind in a fervent, hardcore pounding. The room filled with our primal grunts and moans as I thrust into her, my need for release overpowering any sense of propriety. Our parents' footsteps grew louder, but I couldn't resist the pleasure coursing through me. In a brief, intense climax, I took her, leaving her breathless and satisfied.
